Sub Total / Total
I am using Access 2000. I am using a form containing three fields:
- Film Quantity
- Contrast Quantity
- Exam Quantity
Once data (a quantity) is entered into the form I have developed a related query/report combination whereby the following calculations are made:
Cost of Film: [Film Quantity]*2
Cost of Contrast: [Contrast Quantity]*50
Cost of Exam: [Exam Quantity]*400
For each of the above expressions, I am able to calculate the proper amount on the report, based on the quantity entered.
Here is my problem: I have established another query field called - Total Cost: [Cost of Film]+[Cost of Contrast]+[Cost of Exam]. I have tried to setup the Total row as an expression or a SUM. Neither one will total the three calculated fields.
So what am I doing wrong?
Thanks for any help you are willing to give.

Re: Sub Total / Total
I'm getting a little lost in your question because of the mix of form/query/report. As I understand it, the calculated fields for Cost of Film, etc., are in the query, right?
You say you're using a form with 3 fields, do you mean a table with 3 fields, or a form with 3 controls, and is the query based on the table or the form?
Are you using the query as a report, or do you have a report based on the query? You cannot base a report calculated field on another calculated field, although you can base a query field on a calculated field.
This problem isn't clear:<hr>I have tried to setup the Total row as an expression or a SUM. Neither one will total the three calculated fields.<hr>You have to set it up as an expression so if it doesn't work, what error are you getting or what are you seeing? I've found that calculated fields like<hr>Cost of Film: [Film Quantity]*2<hr>usually behave better in secondary calculations if you fully reference the field. That is, you need [TableName].[File Quantity] in the expression, where tablename is the name of the table or query that contains the File Quantity field.Charlotte
